WOOD CHIPPER AND CRUSHEF?.v

snncrnicATIoN forming part of Letters Patent No. 685,018, dated october 22, 190i.

Application filed May 27, 1901.

To` all whom iz? 11i/ay concern:

Be it known that I, JOHN UNSER, a citizen of the United States, residing at Carthage, in the county of J etierson and State of New York, have invented certain new and useful Improvements in Wood "hippers and Crushers, of which the following is a specization, reference being had to the accompanying drawings, in which similar parts are designated in both views by the same reference characters. f

My invention relates to machines for disintegration of wood for paper manufacture, in which the wood is first divided into chips transversely of -the grain of the wood and these 'chips thereafter broken up, so that the particles of wood are sufcient'ly ne'for subsequent treatment. i

Figure 1 of the drawings is a sectional View substantially .along the axis of the machine,

parts of the machine being shown in eleva-4 tion. Fig. 2 is substantially aside elevation of the machine,parts of the same being broken away to more clearly show the construction. Upon a suitable heavy foundation A,which substantially incloscs the machine, the framing-pieces A, A2, and A3 are'bolted. Suitable bearings in the framingpieces A2 and A3 support a heavy shaft A4, upon whichy areL mounted suitable fast and loose Apulleys A5 and AG. There is also secured fast to this shaft A4 the heavy chippendisk B. This chipper-disk is provided with a number of suitable openings B4, extending radilly of the disk, as is clearly shown in Fig. 2, the

Y outer side of these openings being faced, if

desired, with a suitable steel facing-block B. Secured to thedisk adjacent each of these openings is the chipper-knife B2, bolted securely to the disk by a number of-bolts B3, which support lthe operating, edge of each of theselknivespa-rallel to the disk and project a slight distancebeyondthe surface of the same. 0n the opposite side of the disk a series of channel-irons B6, the same in number as the chipper-knives, are securely bolted,and to the ctner side of these channel-irons, which are arranged radially, y as shown, is bolted Serial No. 62,025. (No model.)

pockets formed between the channel-irons B v and the parallel disks B and B5.

The compound rotating disk is mounted in a cylindrical casing D, which extends about the periphery of the disk and is close to the edge of the same encept at the bottom of the disk, as is shown in Fig. 2, where a suitable extension or disintegrating-chamber D7 is formed by the plates D2 and D4, connecting with the casing. DC chamber D7 is connected with a pneumatic conveying-conduit D5. To the upperside of this disintegrating-chamber there isattached to the chamber-wall D4 the corrugated or roughened plate DG, which maybe of any desired construction formed with suitable grooves or corrugation's, but which I prefer This disintegrating.

to form with a series of pyramidal -projecp tions, as shown in Fig. l; Justbelow the chipper-disk there is arranged in this disintegrating-chamber theadj ustable guide-plate E, which is rigidly attached to the shaft E',

mounted in suitable bearings and to which is attached the lever E2. The adj usting-rod ES is pivoted to this lever and is adapted to be fastened in any desired position by locking means which engages any one of a series of locking-recesses E4 in the upper part of said rod.

It will be noticed, of course', that the side v plate D, secured to the framing member Ag, serves to support the disintegrating-chamber and the casing D', while the plate .D3 serves to close the opposite side of the disintegrating-chamber and projects upward sufficiently to make such casing practically air-tight. To the `framing member Aais secured the guide-trough C, in which the wood in the form of logs O or otherwise is fed downward into contact with the chipper-disk in any desired manner, as is well known in this art.

The operation of my device is as follows: A log C is fed up tothe chipper-disk while the said disk is rotated at a rapid rate by the drivingpulley A5, the chipping-knives B2 projecting slightly from the surface of the disk to remove a chip` from the end of the log C. These chips pass through the openings B4 into the chambers formed by the radial channel-irons B in connection with the two rotary disks. The centrifugal force acting upon these chips tends to throw them outward; but the outward movement of the chips is limited by the inclosing casing" B', which is supported sufficiently close to the periphery jef the disks 'so that the chips cannot escape until the disintegrating-ehamber D7 is reached. At that point the chips are thrown tangentially from the chamber and, guided as far as necessary by the plate E, are thrown violently against the disintegrating-plate D, where they are thoroughly broken up. The pieces are carried forward through the pneumatic conduit .D5 by the blast of air, which, entering the central opening Bl in the disk B5, is constantly driven into the disintegrating-chamber by the fan action of the division-pieces or channel-irons B6. The exact position of the disintegrating-plate D6 may be varied according to circumstances, andv it may be inclined Vat a dilferent angle relative te the periphery of the disks at this point, so that the chips will impinge upon this plate with more or less force. Instead of the exact construction which I have shown for secur-l ing the chambers in the chipper-disk any `0ther suitable arrangement might be used. Forinslance, channels might be formed adjacent each one of the openings B4 and communicating with the central opening B7 and also with the periphery by a disk of any desired shape. lThese channels might be formed of rectangular or circular cross-section and might be convcniently constructed by bolting heavy tubes of the desired shape to the chipper-disk Il.

I do not wish to be limited lo the exact construction of chipper-disk which I have disclosed. The knives might Vbe arranged in a revoluble disk. in a diferent'way from that which I have disclosed, as is jwcll known in this art. Indeed, the chips might be formed from the material in any way and by any mechanism and might be thereafter disintc- I grated by the centrifugal action which l enrploy.

It is of course understood that parts of my invention might be used apart from the rest and that it is not necessary to employ all of the device which l have shown in thedra\ ings and described. 'lhc exact scope of my invention will be pointed outiu the appended claims.
